The etching machine is further provided with a plurality of liquid absorbing mechanisms for absorbing liquid medicine which remains on the upper surface of the plates. According to the vacuum etching machine, liquid medicine on the upper plate surface can be discharged timely through the plurality of the liquid drawing mechanisms, etching uniformity on the upper plate surface is enhanced, route etching factors of the upper plate surface is improved, and the whole etching speed is increased.
Description
Technical field
The utility model relates to the circuit card manufacture field, relates in particular to a kind of vacuum etching machine.
Background technology
Existing etching machine comprises: fuselage, on spray frame, spray assemblies such as frame and conveying roller down.Its principle of work is following: produce plate and be placed on the upper and lower spray frame of process on the conveying roller, the liquid medicine that the spray frame sprays etches away the material that does not block with resist layer of producing the upper and lower surface of plate, obtains required production printed line road.There is following shortcoming in existing etching machine: the liquid medicine that in etching process, is sprayed onto upper face is because of can not in time draining; Can be cumulative in the centre that produces plate; Influence etching speed; The ponding of each position exists different, also can there are differences the degree that stops of last spray, causes the etching of whole production plate upper face inhomogeneous; Last spray frame is sprayed at the liquid medicine of production plate face because of can not in time draining, and the liquid medicine that can cause spraying can not be sprayed directly on the production printed line road, can increase the circuit side etching quantity, reduces the etching factor of circuit.
The utility model content
The utility model embodiment technical problem to be solved is, a kind of vacuum etching machine is provided, and can in time siphon away the soup of the upper face of producing plate.
In order to solve the problems of the technologies described above; The utility model embodiment has proposed a kind of vacuum etching machine; Comprise: body, processing solution tank, be arranged at cooperatively interacting of internal body and carry the last conveying roller and the following conveying roller of plate and last spraying mechanism and the following spraying mechanism that is arranged at the above and below of plate mobile route respectively, said etching machine also comprises a plurality of liquid sucting mechanisms that are used to draw the liquid medicine that residues in the plate upper surface.
Further, said liquid sucting mechanism comprises: the pump housing, a plurality of ejector that is connected with the exit end of the pump housing and a plurality of is connected with the gas tube of corresponding ejector respectively passes through the imbibition cutter that negative pressure of vacuum that jet produces is drawn the liquid medicine of upper face.
Further, the jet pipe of the entrance end of the said pump housing and said ejector all is communicated with said processing solution tank.
Further, the two ends of said imbibition cutter are installed on said two roller shafts going up conveying roller and with said roller shaft is upper and lower through web member respectively and move.
The vacuum etching machine of the utility model can siphon away the liquid medicine of discharging the plate upper surface in time through liquid sucting mechanism is set, and improves the etched homogeneity of upper face, improves the upper face circuit etching factor, improves whole etching speed.
Description of drawings

Fig. 2 is the side-view of the vacuum etching machine of the utility model embodiment.
Embodiment
The vacuum etching machine that sees figures.1.and.2 to the utility model describes.
The vacuum etching machine of the utility model as shown in the figure comprises: body 2, processing solution tank 3, go up conveying roller 4, down conveying roller 5, go up spraying mechanism 6, spraying mechanism 7 and a plurality of liquid sucting mechanism down.Wherein, processing solution tank 3, go up conveying roller 4, down conveying roller 5, go up spraying mechanism 6, spraying mechanism 7 and liquid sucting mechanism all are arranged at body 2 inside down.Form a conveyor surface between last conveying roller 4 and the following conveying roller 5, plate is positioned between conveying roller 4 and the following conveying roller 5, cooperatively interact and can plate be transported to the other end from an end of body 2 through last conveying roller 4 and following conveying roller 5.Last conveying roller 4 is formed by roller shaft with the many rollers that roller shaft is rotationally connected with following conveying roller 5.Last spraying mechanism 6 and following spraying mechanism 7 are arranged at the above and below of plate mobile route respectively, form by shower and a plurality of nozzles that are arranged on the shower.When plate is placed on when carrying between conveying roller 4 and the following conveying roller 5; The liquid medicine that the spray header of last spraying mechanism 6 and following spraying mechanism 7 sprays does not etch away the upper and lower surface of plate with the material that resist layer blocks, and then obtains required line pattern.The liquid medicine that sprays flows into treated can be recycled in processing solution tank 3 backs.
Liquid sucting mechanism is used to draw liquid medicine that the upper surface of plate converges and liquid medicine is entered processing solution tank 3.Liquid sucting mechanism comprises: the pump housing 11, a plurality of ejector 12 and a plurality of imbibition cutter 13 that is connected with corresponding ejector 12 respectively.The entrance end 111 of the pump housing 11 is connected with processing solution tank 3, and the exit end 112 of the pump housing 11 is connected with the water-in of a plurality of ejectors 12 respectively.The jet pipe 122 of ejector 12 is connected with processing solution tank 3, and the gas tube 121 of ejector 12 is connected with corresponding imbibition cutter 13 through conduit, and conduit comprises can be with imbibition cutter 13 upper and lower mobile flexible conduits.During practical implementation; The pump housing 11 is extracted liquid medicine out from processing solution tank 3; And at a high speed injecting processing solution tank 3 from the jet pipe 122 of ejector 12, swiftly flowing soup forms vacuum in the mixing chamber of portion within it during through ejector 12, this moment ejector 12 mixing chamber and outside formation negative pressure; Imbibition cutter 13 sucks the liquid medicine on the outer panel gas tube 121 and injects processing solution tank 3 through jet pipe 122, and then has realized that the absorption of plate upper surface liquid medicine, discharge utilize again.The two ends of imbibition cutter 13 are installed on two roller shafts of conveying roller 4 and with roller shaft is upper and lower through web member 8 respectively and move, and to keep the distance of imbibition cutter 13 and the upper face of plate, reach best soaking effect.
The vacuum etching machine of the utility model can be discharged the liquid medicine of upper face in time through liquid sucting mechanism is set, and improves the etched homogeneity of upper face, improves the upper face circuit etching factor, improves whole etching speed.The liquid medicine of drawing simultaneously sprays in the processing solution tank 3 through ejector 12, can be recycled after handling.
The above is the embodiment of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also are regarded as the protection domain of the utility model.
